Testing Nitrate Limited

Not sure if anyone has come up with a answer to this but, everyone i spoke to couldn't solve it many people have hit this problem leaving phosphates high. I will share the only way i know to overcome it, I started dosing red sea reef energy part A & B. This made my nitrates higher without affecting phosphates. Now i have successfully dropped my phosphates with this method, if anyone could shed some light on a method they use please do.

I have not experienced this except with the UAS scrubber on my 150G only so I built and installed the tried and true water fall version last 8 Days ago. I also had an issue with not being able to get the nitrate under 20-30 as well. I grew algae by the hand fulls in a weeks time but to no success. I gave it several months but have Kicked the UAS to the side on my 150G. Now my 10G is a different story, its great with a UAS and nothing is limited.

Thats interesting im using floyds l2 and as soon as my screen growth went green my nitrates dropped to undetectable by salifert kit & i feed alot. My problem was the live rock it leeched phos for months.

I was running an L2 on the dentist's office tank for several months and before than a larger scrubber and could not maintain P < 0.06. After recently changing to a higher flow pump, my P is < 0.02 and N < 0.2.

Flow can make a big difference, so if you have a mature screen, up the flow a little bit (if you can), week by week, and see if there is an effect.

I have thought about this to. I purposely built this 150G screen skinny as my 40G is wide. I wondered if flow or turn over had any effect and figured it was feasible. I will be able to have a pretty good test base as both scrubbers are pretty close and I treat the tanks about the same proportionally.

Crashmushroom was one of my first international customers (back in June) and I believe still holds the record for fastest-to-green I have ever seen. Here are pics he sent me of day 10 and day 11 on his scrubber, from a bare screen:
